Abstract

The eye’s intricate oculomotor system is conceptually difficult for students to understand both anatomically and functionally. This is especially true for the prime movers of the eye, the extraocular muscles, which are perhaps the least understood components by new students. This is problematic given that this group of muscles represents the most common site of clinical intervention in the treatment of ocular motility disorders and other diseased states. The objective of this project is to develop a novel, three‐dimensional (3D) exploratory tool that may be paired with an electronic learning module creating an interactive 3D model of the human eye, extraocular muscles, and associated cranial nerves. It is hypothesized this online learning module will enhance students’ anatomical understanding and functional application of the oculomotor system, compared to students using equivalent traditional educational materials. Construction of the 3D model will utilize data from the Visible Human Project (VHP) dataset that will be segmented using Amira 5.2 software. Further editing will be performed using MeshLab software. The completed model will be imported into Blender 2.5 software to generate animations of eight extraocular muscle actions, each originating from the primary position. Undergraduate medical student preference and post‐test performance will be undertaken to assess the 3D learning module in comparison to the conventional 2D learning materials. Results from this study will help inform educators and technical learning specialists about the merits of interactive learning materials.

More than Meets the Eye: An Interactive 3D Model of the Eye for Enhanced Learning of the Oculomotor System

The eye’s intricate oculomotor system is conceptually difficult for students to understand both anatomically and functionally. This is especially true for the prime movers of the eye, the extraocular muscles, which are perhaps the least understood components by new students. This is problematic given that this group of muscles represents the most common site of clinical intervention in the treatment of ocular motility disorders and other diseased states. The objective of this project is to develop a novel, three‐dimensional (3D) exploratory tool that may be paired with an electronic learning module creating an interactive 3D model of the human eye, extraocular muscles, and associated cranial nerves.
